Procedure

A microwave vessel was charged with 2-(2,5-dichloro-pyrimidin-4-ylamino)-3-fluoro-N-methyl-benzamide (50.0 mg, 0.159 mmol), 7-amino-1-(2-methoxy-ethyl)-1,3,4,5-tetrahydro-1-benzazepin-2-one (45 mg, 0.19 mmol), 10-camphorsulfonic acid (5.0 mg, 0.022 mmol) and isopropyl alcohol (2 mL) and heated at 120° C. for 30 minutes in a microwave reactor (sealed vessel). The reaction was diluted with water (10 mL) and extracted into EtOAc. The organic layer was washed with NaHCO3 and dried by passing through a funnel filled with MgSO4. The filtrate was evaporated and the residue purified by chromatography (silica gel, 5% NH4OH in MeOH gradient with DCM). The appropriate fractions were combined and evaporated to afford a solid that was triturated with ether (2×2 mL) and yielded product (39.0 mg, 48%) as a white powder that had the following properties: m.p.=146-147° C., bubbled, remelt at 184-187° C.; LC/MS (ESI+): 513 (M+H); 1H-NMR (CDCl3, 400 MHz): δ 8.90 (s, 1H), 8.10 (s, 1H), 7.4-7.2 (m, 5H), 7.10 (d, J=8.5, 1H), 7.0 (s, 1H), 6.2, (s, 1H), 3.7-4.2 (m, 2H), 3.55-3.47 (m, 2H), 3.30 (s, 3H), 2.95 (d, J=4.9, 3H), 2.9-2.4 (m, 2H), 2.3-2.2 (m, 2H), 1.8-2.3 (m, 2H).
